You are logged on in another language than German.

You face the following problem:

When you maintain partner functions, for example in a customer master record or in a sales order, the system issues the error message "In table TPAER, the entry X1, X2, ... is missing" (F2100). The descriptions X1 and X2, in this case, represent the individual partner functions.

When you create sales orders, certain partners are not determined even though the partner maintenance in the customer master and in the partner determination procedure are correct.
